To {ti/ 107mm/ it 71mg/ concern:

Be itknown that I, OLIVER G. KIPP,a citizen of the United States, residing at Rochelle, in the county of Ogle and State of Illinois, have invented certainv new and useful Improvements in Lubricators, of which the following is a speciiication.

The object of this invention is to construct a lubricator for'explosive-engines in which a positive feed is secured and which is operated by the engine.

In the accompanying drawings, Figure l is a vertical section taken through the complete lubricator on dotted line a, Fig. 2. Fig. 2 is a vertical section on dotted line b,.Fig. 1. Fig. 3 is an elevationr showing the pawl-andratchet feed mechanism. Fig. 4 is avertical section showing'one of the plungers in the act of dischargingoil into the duct leading to the engine. Fig. 5 is a transverse vertical section showing the position `of the parts when the upper plunger is fully extended. Fig. 6 is an isometrical representation of the plug. Fig. 7 is an isometrical representation of the cam. Fig. 8 shows different views of the cam.

An oil-reservoiremployed in connection with my improvements is of the usual con-l struction, having the end caps l and 2 con-I nected by aglass 3. Below the end cap -2 and connected therewith extends a cylinder 4, havingits open end screw-threaded and its other endjhaving a horizontal opening and provided with `a stufng-box 5. From the cylinder extendsascrew-threaded extension 6, having a Vertical opening 7, commue nicating with the cylinder,and a vertical opening 8 connects Vthe cylinder with the oil-reservoir. A cylindrical head 9 is located within thecylinder and. is provided with three lengthwise pockets 10. Fromone end of this cylinder-head extends a guidelhandfrom Vits other end-'extends a shaft `12,.passing through the Vstufling box 5. Within each pocket'is located a spiral spring 13 and a plu nger 14, and an opening 15 extends from the pocket in line with the verticalopenings 7 and 8,`extending from the cylinder. Vithin the screw-threaded'openend of the cylinder is inserted a plug 16, having a socket-17, receivin g the projection 11 of the head 9, located within the cylinder. A radial groove 18 is Serial No. 55.981. (Nomodel.)

formedin the inner face of the plug, and an adjusting-screw 19 is supported by the plug and projects into the radial groove. A cam 20 has a central opening 21, and from its rear face extends a projection 22, Aadapted to t within the radial groove 18 of the plug 16, and its central opening receives the projection 11, extending from the head located within the cylinder.

An intermittent rotary movement is imparted to the shaft l2, and the means for imparting such movement consists of the sawtoothed wheel23, secured to the shaft. An arm 24 is loosely mounted on the shaft and 'supports a dog'25 at its upper end.` From the lower end of this arm extend two projections 26rand a weight 27. An arm 2Stisl'o'osely mounted on the shaft and is located between the projections 26 of the arm`i24, and this arm 'has' a connection with some moving part of the engine in a manner to oscillate it. An adj listing-screw 29 has a connection with one ofthe projections 26. 30 hold the arms 24 and 28 from lengthwise movement on the shaft, but permitting their oscillatory movement. VAs the arm 2S is oscillated by the `engine it Lwill alternately engage one ofthe projections26 and the adj nsting-screw 29 of the arm 24, thereby imparting movement to this arm, and cause the dog 25 to engage the teeth of the wheel, 23 and move the wheel, and by means of the screw 29 the movement imparted to the arm 24V can be varied, so thatthe dog will engage one tooth or a greater number of teeth, and the weight 27 will keep the'dog in engagement with a tooth after the arm 28. has beenremoved from its engagement withthe set-screw. As the shaft 12-is' intermittent-ly rotated the head 9 will be likewise rotated and the plungers 14 W-ill be forced in against the action of their springs fdurin'g a portion of a revolution of the head est and thinnest portion of the cam. During the upward portion of the movement of the plungers-that is, from the thickest por` tion of the wedge-shaped block to the thin- A washer and screw- IOC) g nest portion thereof-the springs Will force the plungers out, thereby creating a vacuum Within the pockets in the space occupied by the springs, and when the openings 15 of the pockets enter the vertical opening 8 connecting with theoil-reservoir a communication will be formed between the pocket and oilreservoir and oil from the reservoir will be drawn into the pocket and will continue to be drawn in until the opening of the pocket has passed out of communication with the opening leading from the oil-reservoir. In the downward portion of the movement of the plunger it will be forced in until the opening of the pocket has passed the opening leading to the engine-cylinder, and the oil Within the pocket will be expelled therefrom during the time the opening of the pocket is in communication with the opening leading to the en gine` By locating the thickest and thinnest portion of the cam on the dotted lines 3l the pocket will continue todraw in oil untilits opening has passed out of communication with the opening leading from the oil-cup and continue to force oil lout of the pocket until its opening has passed out of communication with the opening leading to the engine.

In the drawings Ihave shown three plungers; but it is evident that more or less can be used Without departing from the scope of my in' vention.

By means of the screw 19 the thickest portion of the cam 20 'can be moved so as to force the plungers in a greater extent, thereby eX- pelling a greater quantity of oil and creating a greater vacuum which will receive a greater quantity of oil from the oil-reservoir. The opening in the cam 20 is somewhat larger than the shaft which supports it, which allows a Wabbling movement of the cam.

l claim as my inventionl. The combination of an oil-reservoir, an outlet-passage leading from the reservoir, a cylindrical opening having a communication with the outlet-passage, a discharge-opening leading from the cylindrical opening, a cap for the cylindrical opening, a head located Within the cylindrical openinghaving a shaft extension, means for imparting an intermit-v for the cylindrical opening, a head located within the cylindrical opening having a shaft extension, means for imparting an intermittent rotary movement to the shaft, the head having a series of lengthwise chambers each having an opening through the periphery of the head, each chamber having a plunger, a spring for each plunger moving it in one direction and a cam moving the plungers in the opposite direction, the cam being adjustable.
